Robotic Nudges: The Ethics of Engineering a More Socially Just Human Being

Robots are becoming an increasingly pervasive feature of our personal lives. As a result, there is growing importance placed on examining what constitutes appropriate behavior when they interact with human beings. In this paper, we discuss whether companion robots should be permitted to “nudge” their human users in the direction of being “more ethical”. More specifically, we use Rawlsian principles of justice to illustrate how robots might nurture “socially just” tendencies in their human counterparts. Designing technological artifacts in such a way to influence human behavior is already well-established but merely because the practice is commonplace does not necessarily resolve the ethical issues associated with its implementation.     

On ascetic practices and hermeneutical cycles

Sports reflection is rather locked into a binary view of narrow and broad internalists. Narrow internalists, or formalists, argue that sports are solely constituted by their rules: the ‘autotelic’ stance. Broad internalists, or interpretivists, on the other hand, reason that sport is more than just a lusory end in itself. This paper will revitalize reflection on sports as a locus of the human condition by breaking through this binary opposition. It will focus on the positive aspects of the concept of ‘agon’ (suffering, enduring). As an ‘agonal’ or competitive social practice, sport may be a means to a ‘heterotelic’ end that surpasses the concept of sport as self-referential play: seeking knowledge, understanding the human condition and cultivating virtue. As such, self-improvement through repetitive practice (‘askesis’) has always been a key theme of human existence. Our ‘ascetic planet’ is inhabited by individuals who are constantly and relentlessly training themselves for the better. This may be self-focused, but it may also have a broader scope: we train ourselves to become better humans, contributing to a just and sustainable society. Paradoxically, however, this will only work when we become aware of our exercises as forms of life that engage the practising person. A hermeneutics of endurance cycling can enrich our understanding of this sports activity as a form of asceticism. As such, it will elaborate a view on cycling as an upwardly oriented ‘spiral’ that can contribute not only to self-knowledge and self-improvement on the individual level (‘metanoia’), but also to an ‘ecosophical renaissance’ on the collective level.     

Alternative Approaches to Addressing Non-Normal Distributions in the Application of IRT Models to Personality Measures

It is generally assumed that the latent trait is normally distributed in the population when estimating logistic item response theory (IRT) model parameters. This assumption requires that the latent trait be fully continuous and the population homogenous (i.e., not a mixture). When this normality assumption is violated, models are misspecified, and item and person parameter estimates are inaccurate. When normality cannot be assumed, it might be appropriate to consider alternative modeling approaches: (a) a zero-inflated mixture, (b) a log-logistic, (c) a Ramsay curve, or (d) a heteroskedastic-skew model. The first 2 models were developed to address modeling problems associated with so-called quasi-continuous or unipolar constructs, which apply only to a subset of the population, or are meaningful at one end of the continuum only. The second 2 models were developed to address non-normal latent trait distributions and violations of homogeneity of error variance, respectively. To introduce these alternative IRT models and illustrate their strengths and weaknesses, we performed real data application comparing results to those from a graded response model. We review both statistical and theoretical challenges in applying these models and choosing among them. Future applications of these and other alternative models (e.g., unfolding, diffusion) are needed to advance understanding about model choice in particular situations.     

Evaluation of a participatory,competency‐based model of staff training in a community habilitative setting

This study evaluated a participatory model of staff training within a community habilitative setting for adults with developmental disabilities. The objectives were to formulate an approach to training that was not time intensive, included multiple instructional methods, and incorporated all levels of staff involvement. Senior administrative, middle‐level supervisory, and direct‐care personnel comprised a committee that designed and implemented a training program that targeted performance and verbal report competencies required by ‘on‐line’ staff. Training consisted of corrective feedback, modeling, rehearsal, and practice procedures that were carried out with three individuals in a multiple baseline design across sets of target competencies. The training program was effective in establishing staff competencies although individual learning effects were revealed. The implications of these findings for the design of staff training programs within human service agencies are discussed. Copyright © 2001 John Wiley & Sons, Ltd.     

Prejudice toward immigrant workers among Dutch employees: integrated threat theory revisited

Integrated Threat Theory (ITT) (Stephan & Stephan, 1993 , 1996 ) describes four types of threats as mediators in the relation between antecedent factors (previous intergroup conflict, intergroup contact, status inequalities, in‐group identification, knowledge about the out‐group, and intergroup contact) and prejudice. The four mediating types of threats, which influence prejudice according to ITT are: intergroup anxiety, negative stereotyping, realistic and symbolic threats. In this study, the ITT model was tested using structural equation modeling on data collected in sample of 187 Dutch employees. Two alternative explanatory models are proposed in which, first intergroup anxiety and then negative stereotyping mediate the relation between the other ITT threats and prejudice. The data show a good fit with the model in which negative stereotypes are considered as mediator variable. The implications of these findings for ITT are discussed in the context of recent theoretical developments in the study of stereotypes and prejudice. Copyright © 2006 John Wiley & Sons, Ltd.     

Language Impairment and Sexual Assault of Girls and Women: Findings from a Community Sample

Both children and adults with disabilities face increased prevalence of abuse and assault, including sexual assault. Women and girls are disproportionately the victims of sexual assault in both disabled and nondisabled populations. Communication difficulties have been identified as a factor that may increase the vulnerability of individuals with disabilities to sexual assault. However, few studies have examined whether language impairment increases risk for sexual assault. This study reports on a community sample of children with speech or language impairment, followed to age 25. Sexual assault history was assessed based on two questions from the Composite International Diagnostic Interview Posttraumatic Stress Disorder module. Women with language impairment (n = 33) were more likely than women with unimpaired language (n = 59) to report sexual abuse/assault, controlled for socioeconomic status. Sexual assault was associated with higher rates of psychiatric disorders and poorer functioning. Women with neither language impairment nor a history of sexual assault had fewer psychiatric disorders and higher functioning than women with language impairment and/or a history of sexual assault.     

Examining Externalizing Behavior Trajectories of Youth in Group Homes: Is there Evidence for Peer Contagion?

Although concerns about peer contagion are often cited in critiques of group treatments for troubled youths, few studies have examined the effects of exposure to deviant peers in residential group care settings. This study used administrative data of youth served at Boys Town, a nationally-known group care provider. Using latent class growth analysis, this study identified the externalizing behavior trajectories of youth in group care as well as the behavior trajectory of the peers with whom they lived, assessed the relationship between youth trajectory classes and individual and peer group characteristics as well as the relationship between an individual youth’s behavior pattern and the behavior pattern of proximal peers. Several results suggested the presence of peer contagion in group care: a trajectory class of gradually increasing externalizing behavior problems, the strength of deviant peer density in predicting an individual youth’s externalizing behavior trajectories and significant associations between behavior patterns of youth and proximal peers. While there is some evidence that suggests an increase in problem behavior during care, results from this study indicated that over 90% of the youth did not have an increase in problem behaviors and that positive peer influences may also be protective and inhibit problem behaviors.     

Forget Transmitted Memory: The De-traditionalised ‘Religion’ of Prem Rawat

This article uses the case study of Prem Rawat, a teacher of Indian origin who arrived in the West in 1971 and inspired several organisations, including Divine Light Mission, Elan Vital, and The Prem Rawat Foundation for the dissemination of his teachings. Identifying Prem Rawat as a contemporary form of a solitary Sant unconcerned with organisational forms or institutionalised religion and displaying considerable iconoclasm with regard to ritual and doctrinal dimensions, the article offers fresh insights into the debate in the study of religion between those who maintain that religion exists as a sui generis category and those who argue that religion is merely a sub-set of cultural phenomena. In particular the article focuses on the work by Danièle Hervieu-Léger who argues that religion exists when ‘the authority of tradition’ has been invoked ‘in support of the act of believing’.
